The saving words and deeds of Jesus Christ are the foundation of what he would communicate in the Sacraments through the ministers of the Church.
The sacraments the Church celebrates are signs of grace that make a deeper reality present to us. One reality we encounter through the sacraments is Christ’s presence in the Church community, his body.
Guided by the Holy Spirit, the Church recognizes the existence of Seven Sacraments instituted by the Lord.They are the Sacraments of Initiation (Baptism, Confirmation, the Eucharist), the Sacraments of Healing (Penance and the Anointing of the Sick), and the Sacraments at the Service of Communion (Marriage and Holy Orders). Through the Sacraments, God shares his holiness with us so that we, in turn, can make the world holier.
